The leading neoconservative think tank Foundation for Defense of Democracies is functioning as an agent of the Israeli government, Al Jazeera’s forthcoming investigation on the US Israel lobby will reveal.

According to a source who has seen the undercover documentary, it contains footage of a powerful Israeli official claiming that “We have FDD. We have others working on this.”

Sima Vaknin-Gil, a former Israeli military intelligence officer, is said to state that the foundation is “working on” projects for Israel including “data gathering, information analysis, working on activist organizations, money trail. This is something that only a country, with its resources, can do the best.”

Under the Foreign Agents Registration Act, commonly known as FARA, US organizations and individuals who work on behalf of foreign governments are required to register with the counterintelligence section of the Department of Justice.

A search on the FARA website shows that the Foundation for Defense of Democracies is not registered.

Al Jazeera’s film reportedly identifies a number of lobby groups as working with Israel to spy on American citizens using sophisticated data gathering techniques. The documentary is also said to cast light on covert efforts to smear and intimidate Americans seen as too critical of Israel.

Israel lobby groups have placed intense pressure on Qatar, which funds Al Jazeera, to shelve the film, fueling speculation it may never be aired.
